First Epistle of Peter in the context of "Born again (Christianity)"

The authorship of the Petrine epistles (1 Peter and 2 Peter) is a question in biblical criticism, parallel to that of the authorship of the Pauline epistles, in which scholars have sought to determine the exact authors of the New Testament letters. The vast majority of biblical scholars think the two epistles do not share the same author, due to wide differences in Greek style and views between the two letters. Most scholars today conclude that Peter the Apostle was the author of neither of the two epistles that are attributed to him.

Quakers are people who belong to the Religious Society of Friends, originally known as simply the Society of Friends, a historically Protestant Christian set of denominations. Members refer to each other as Friends after John 15:14 in the Bible. Originally, others referred to them as Quakers because the founder of the movement, George Fox, told a judge to "quake before the authority of God".

The Friends are generally united by a belief in each human's ability to be guided by the inward light to "make the witness of God" known to everyone. Quakers have traditionally professed a priesthood of all believers inspired by the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity, as well as Nontheist Quakers. To differing extents, the Friends avoid creeds and hierarchical structures. In 2017, there were an estimated 377,557 adult Quakers, 49% of them in Africa followed by 22% in North America.

Papyrus 72 is the designation used by textual critics of the New Testament to describe portions of the so-called Bodmer Miscellaneous codex (Papyrus Bodmer VII-VIII), namely the letters of Jude, 1 Peter, and 2 Peter. These three books are collectively designated as 𝔓 in the Gregory-Aland numbering of New Testament manuscripts. These books seem to have been copied by the same scribe. Using the study of comparative handwriting styles (paleography), the manuscript has been assigned to the 3rd or 4th century.

Although the letters of Jude (P.Bodmer VII) and 1-2 Peter (P.Bodmer VIII) in this codex do not form a single continuous text, scholars still tend to refer to these three texts as a single early New Testament papyrus.

The Good Shepherd (Greek: ποιμὴν ὁ καλός, poimḗn ho kalós) is an image used in the pericope of John 10:1–21, in which Jesus Christ is depicted as the Good Shepherd who lays down his life for his sheep. Similar imagery is used in Psalm 23 and Ezekiel 34:11–16. The Good Shepherd is also discussed in the other gospels, the Epistle to the Hebrews, the First Epistle of Peter and the Book of Revelation.

Regeneration, while sometimes perceived to be a step in the ordo salutis ('order of salvation'), is generally understood in Christian theology to be the objective work of God in a believer's life. Spiritually, it means that God brings a person to new life (that they are "born again") from a previous state of separation from God and subjection to the decay of death (Ephesians 2:5). Thus, in Lutheran and Roman Catholic theology, it generally means that which takes place during baptism. In Calvinism (Reformed theology) and Arminian theology, baptism is recognized as an outward sign of an inward reality which is to follow regeneration as a sign of obedience to the New Testament; as such, the Methodist Churches teach that regeneration occurs during the new birth.

While the exact Greek noun for 'rebirth' or 'regeneration' (Ancient Greek: παλιγγενεσία, romanized: palingenesia) appears just twice in the New Testament (Matthew 19:28 and Titus 3:5), regeneration in Christianity is held to represent a wider theme of re-creation and spiritual rebirth, including the concept of "being born again" (John 3:3–8 and 1 Peter 1:3; regeneration is also called the "second birth"). In some schools of Christian thought, it is held that when a person expresses belief in Jesus Christ for their salvation, they are then born of God, "begotten of him" (1 John 5:1). As a result of becoming part of God's family, the person becomes a different and new creature (2 Corinthians 5:17).
